Features

  • Higher-Capacity Hybrid Core — Rated at 5.5kW with a 10kVA surge, it handles broader home loads than entry-level units while keeping a 24V battery system.
  • 9kW MPPT Solar Harvesting — A 60-450Vdc MPPT range and 160A charge current let the inverter draw up to 9kW from the PV array into the battery.
  • Pure Sine Wave Home Power — It outputs 208-240Vac pure sine wave electricity that runs appliances and electronics safely, with a 10ms backup transfer during outages.
  • 24V Battery Flexibility — Supporting lithium and lead-acid 24V batteries, it adapts storage choice to budget and cycle-life priorities.
  • Grid and Solar Coordination — The hybrid logic charges from solar first, then grid if needed, and discharges the battery to cover evening and backup loads.
  • Communication Interfaces — RS232, RS485, and USB plus an optional WiFi HMI connect the inverter to external monitoring and control equipment.

Applications

  • Larger Residential Solar: Covers higher home consumption with battery backup.
  • Home Energy Storage: Shifts daytime solar to evening and backup use.
  • Backup Power: Protects essentials through outages with fast transfer.
  • Small Commercial: Supports shops and offices with self-consumption.
  • Rural Homes: Delivers reliable AC where grid is weak or absent.
  • Solar Self-Consumption: Increases on-site solar use and bill savings.

Solar Conversion & MPPT Performance

The SW-5.5KW-24V is built around a 9kW MPPT solar stage with a 60-450Vdc operating range and 500Vdc open-circuit limit, enabling larger panel strings and strong harvesting. A 160A charging path feeds that energy into the 24V battery quickly and efficiently.

The inverter then converts solar and battery DC into stable 208-240Vac pure sine wave output at up to 5.5kW, with a 10kVA surge for demanding starts. By using solar and stored energy before grid power, it raises a household's self-consumption.

Grid, Battery & System Integration

This hybrid inverter unifies PV, a 24V battery, and grid supply, charging the battery from solar or AC and discharging it for evening use and backup. One device manages generation, storage, and delivery.

RS232, RS485, and USB interfaces with an optional WiFi HMI support connection to monitoring equipment, while IP21 protection and a -10C to 60C operating range suit indoor residential and light commercial settings. A 10ms transfer sustains essential loads during outages.

Frequently Asked Questions

Is the 5.5kW inverter suitable for a bigger home?

Yes. With 5.5kW output and a 10kVA surge, it covers more appliances and larger evening loads than smaller hybrid units.

How much solar can I connect?

The MPPT accepts up to 9kW of PV and 500Vdc open-circuit across a 60-450Vdc range, so size your array within those limits.

Does it work with my 24V battery?

It is built for 24V lithium or lead-acid batteries and charges them from solar through a 160A MPPT stage.

What happens during a power cut?

It transfers to battery backup in about 10ms, keeping essential loads running until grid power returns.
